Subject: [PATCH] ASoC: ops: Fix multiple value control type

The commit aa2a4b897132("ASoC: ops: Fix boolean/integer detection for
simple controls") fixes false positives with controls not ending in
" Volume" string. But it now forces boolean type for the multi value
controls. Fix this by adding a max check before assigning types.
